The Fairchild Metro is one of the most popular commuter aircraft in the class up to 20 seats. It is a twin engine turboprop aircraft and is being manufactured by the Fairchild Aircraft Corporation in San Antonio, TX. The fact that the aircraft is faster than its competition and that it is pressurized makes it attractive to commuter airlines. The large rear door makes the aircraft well suited for cargo operators as well. The first prototype of the Metro flew in August of 1969 and the newest version of this aircraft, the Metro 23, which has a higher take off weight, received certification in 1991.
